Where to get Bed Bugs Identified in Contra Costa County

If you believe you have bed bugs and you have a sample that you would like identified, bring or mail it (see below for how to safely transport or mail the sample) to the following locations:

  • Contra Costa County Vector Control
    155 Mason Circle
    Concord, CA 94520-4807
    Monday – Friday 8am–5pm
  • Contra Costa County Department of Agriculture / Weights and Measures
    2366 A Stanwell Circle
    Concord, CA 94520
    Monday – Friday 8am–5pm
  • Contra Costa County Master Gardeners
    75 Santa Barbara Rd., 2nd Floor
    Pleasant Hill, CA 94523-4215
    Monday – Thursday 9am-12 noon

DO NOT mail or transport live bed bugs because that will spread an infestation!

There are several ways to prepare your sample for transport.

  • Pick up the bug using scotch tape and then tape it to a piece of paper.
  • Saturate a cotton ball with rubbing alcohol, pick up the insect with the cotton ball and place it in a plastic bag. Seal the bag.
  • Pick up the bug with a pair of tweezers and drop it into a small container that has a tight-fitting, screw-on lid with a rubber gasket. Cover the specimen(s) with rubbing alcohol and screw the lid on tightly.

If you mail your sample, pack it in a box. Do not mail your sample in an envelope because your container may break. If you have put the bugs in a plastic bag or taped them to paper, they may get crushed in the mail. It is very hard to identify a crushed bug.
